Run Claude Code on your own computer

Why isolation?

Maude runs Claude Code with full system permissions — no approval prompts, no interruptions. This is great for productivity, but it means Claude can read, write, and delete any file it has access to.

Running inside a Docker container keeps your host machine safe. Claude can only access files inside the container.

Step 1 — Create the container

Install Docker Desktop (or OrbStack on macOS), then pick your preferred method:

Copydocker run -d \
  --name maude \
  -p 2222:22 \
  -v maude-projects:/home/maude/projects \
  ubuntu:24.04 bash -c '
    apt-get update -qq && \
    apt-get install -y -qq openssh-server sudo curl git tmux && \
    mkdir -p /run/sshd && \
    sed -i "s/#PasswordAuthentication yes/PasswordAuthentication yes/" /etc/ssh/sshd_config && \
    sed -i "s/PasswordAuthentication no/PasswordAuthentication yes/" /etc/ssh/sshd_config && \
    useradd -m -s /bin/bash maude && \
    chown -R maude:maude /home/maude && \
    echo "maude:secret-password" | chpasswd && \
    echo "maude ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/maude && \
    /usr/sbin/sshd -D
  '

CopyFROM ubuntu:24.04

RUN apt-get update && \
    apt-get install -y openssh-server sudo curl git tmux && \
    mkdir -p /run/sshd && \
    sed -i 's/#PasswordAuthentication yes/PasswordAuthentication yes/' /etc/ssh/sshd_config && \
    sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/' /etc/ssh/sshd_config

RUN useradd -ms /bin/bash maude && \
    echo "maude:secret-password" | chpasswd && \
    echo "maude ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/maude

EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

Copydocker build -t maude-server .
docker run -d \
  --name maude \
  -p 2222:22 \
  -v maude-projects:/home/maude/projects \
  maude-server

This creates an Ubuntu container with:

• SSH server on port 2222
• User maude with password secret-password
• Passwordless sudo (needed for installing packages)
• A persistent maude-projects volume for your code
• Git, curl, and tmux pre-installed

Step 2 — Test the connection

Verify SSH works from your terminal:

Copyssh -p 2222 maude@localhost

Enter the password (secret-password) and you should get a shell. Type exit to disconnect.

Step 3 — Add to Maude

Open Maude and add a new server with these credentials:

Maude will install tmux and Claude Code on first connection. Follow the on-screen steps to authenticate with your Claude account.

Step 4 — Connect from anywhere with Tailscale

The setup above works when your phone is on the same network as your computer (e.g. home Wi-Fi). To connect from anywhere, use Tailscale — a free, zero-config VPN.

Managing the container

Copy# Stop the container
docker stop maude

# Start it again
docker start maude

# Remove it (projects volume is preserved)
docker rm -f maude

# View logs
docker logs maude

Your projects are stored in a Docker volume (maude-projects), so they persist even if you remove and recreate the container.
